:To all whihia; it may concem Be that I, Anons'rn PAGHE, a subjectiof Switzerland, and resident of New York, in the county of-New York and State of New York,' have invented certain new' and useful'lmprovements in Time-Control Apparatus,- of-Which the following is a specification. 1 I p This invention relates to certain mechanica'ijmeans; employed in conjunction with a clock-movemei'itg' whereby time control is'ex-- ercised in 't'hie automatic operati n at set periods, of electrlc switches, gas cocks, water valves and corresponding devices 1 The invention includes setting cpiitrolling an'd'releasing mechanism, and means whereby the release becomes operable cit-beret any set period within an-hour, or atany-set period within a given number of'hours, said release causing the power of the ordinary alarm' spring to operate the switch, cock or valve. In the drawings',Figure 1 is a front view of the apparatus, with the dial removed,

showing the release mechanism; Fig. 2 is a front view showing the mechanism for control within a period of sixty minutes; Fig.

3 is a side elevation of the mechanism, also showing connection with a gas cock and electric light switch; Fig. 4 is a partial side elevation of the inclosed apparatus, and Fig. 5 is, a front view of the dial plate.

My improvements are applicable to anyordinary, cheap clock movement, with an. alarm device, the springwhich actuates the alarm hammer, also serving the new functions contemplated by me. To this end the shaft 1, carrying the alarm'spring 2, is extended through the back plate 3 of the clock, where it connects with and turns the spindle 4' or other moving member of a valve, as 5, to open or close said valve. Also said moving member 4 has an extension 6, to which is attached a lever arm 7 whereby said moving member may be turned in the act of winding up the spring. A further extension, as 9, may connect with and operate an electric light switch, as 10.' I provide certain automatic means to release the alarm spring at a predetermined time, said means including a cam 11, having a notch 12; said cam being carried by the central, or main, clock-shaft 13, which also carries the pointer or hand 14, said hand 14 thus makmg a complete traverse of the dial 15 with each revolution of shaft 13. The arbitrary arrangement of dial 15 which I have devised provides divisions for minutes in its circumference, the reading of said minutes being from right to left,'or opposite to the direction .of travel of the hand. I also divide said minute divisions into four parts,

providing in the whole circumference of the dial 240-divisions of 15 seconds each. The cam 11, in its rotation, presents its notch 12 to the nose 16 of a pawl 17, that is pivoted at 18 to the clock frame, whereby said nose 16 enters said notch once in each revolution of said cam, in this act theupstanding arm .19 of pawl 17, releasing a finger 20 which extends from the alarm shaft 21 toa point in the path of finger 20. Under such release act on the alarm hammer vibrates, and the spring shaft 1 tm ns in the act of operating 'the valve, switch or cock with which it is connected. v

The mechanism thus far described in conjunction with the usual clock mechanism, is suilieient for the utilization of the device when it is desired to set it, say for example to operate after a lapse of 10 minutes; the hand 14 is set to point at the numeral 10 on the dial, and said hand being in fixed alinement with notch 12, will register at zero, or 60, whenthe nose of pawl 17 falls into said notch thereby releasing the alarm and actu-' ating spring.

Additional mechanism, required to increase the period of inaction beyond .one

honris as follows: I provide a gear wheel gear 22 has 30 teeth, and hand 24points to a corresponding dial arrangement 26, whose thirty divisions, each representing one hour read from right toleft. A pivotal pawl 27 is held by spring 28 normally engaged with gear 22, to steady the latter, the pawl 27 ridina out of engagement with a tooth into engagement with the next succeeding tooth with the step by step rotation of said gear. The gear 22 carries a stud: 29 in the radial line of hand 24., said stud contacting with an arm 30 of a two arm lever, which is piv; oted at 31, and whose other arm. 32 terml nates in a pawl 33. Obviously the hand 24 can be set with respect to dial 26 so that stud 29 may be agiven number of teeth or hours away from contact with arm 30. The pawl 33 rides upon the eriphery of a cam 34, which cam is pivoted at 35, and has a handle 36 by which it may be swun and adjusted about its pivot. A spring 37 holds said cam in its normally inoperative position, and returns it to said position when released. Said meets and moves the. arm 30' that the pawl 33 leaves notch 38 and allows cam 34 to be retracted byits'spring. When so retracted, then the 60 minute cam comes into operation. Hence, as anexample the hand 24 may be set at its dial numeral 5, and the hand 14 set at its dial numeral 30, the cam 34 at the same time being swung over to engagement with pawl 33. As a result of this setting the alarm sprin will be released at the lapse of 5% hours. I it be desired to release cam 34 at an earlier period, for a new setting, then the spring push piece 40 should be pressed inwardly causing it to shift pawl 33 out of engagement with notch '38, having-the desired result.

As a means for setting the hands 14 and 24, I provide a rod 41, terminating at its upper end in a knurled head 42, and having a. bevel gear 43 at its lower end, said gear 'which may be rotated t meshing with a bevel gear 44 on shaft 13,

ereby.

Various applications of the power of the alarm spring, controlled as described, will occur to the user, whether such usesbe in control of fluid valves or cocks or electrical switches, for cooking, light, heat or power, and whether in turning on the supply or in shutting it off.

I claim:

An alarm clock having an alarin spring shaft, a control device operated by said shaft, a cam on. the center clock shaft, said cam having a notch, a pawl adapted to enter said notch, an arm extending from said pawl,

and a finger upon the alarm hammer shaft in the path of said a'rm,'together with a gear wheel carrying a pointer, alspur upon said cam adapted to mesh with said gear to move it the space of one tooth with each revolution, a stud upon said gear wheel, a two armed pivotal lever, one arm thereof in the ath of 'said stud, a ivotal cam having a slioulder 'to restraint e'alarm spring, a notch in said pivotal cam to reeive'a pawl on the other arm of the pivotal leverand means for setting said-gear wheel whereby through the aforesaid instrumentalities the alarm spring is released at a predetermined point in the rotation of the gear wheel;
